SPECIFICATION forming part of Letters Patent N 0. 679,378, dated July30, 1901. Application filed November 2, 1900. Serial No. 35,197. (Nomodel.)

.Z'o aZZ whom it may concern:

Be it known that I, HENRY D. HIBBARD, a citizen of the United States,residing in Piainfield, in the county of Union and State of New Jersey,have invented certain new and useful Improvements in Looking Mechanismfor Safes or Vaults, of which the following is a specification.

This invention relates to locking mechanism for safe or vault doors, theobject being to provide an improved organization of time and combinationlock mechanism and also to provide an improved organization of time andcombination lock mechanism particularly effective in connection with theimproved locking or bolting mechanism shown and described in mycontemporaneouslypending application, Serial No. 16,402, now Patent No.662,455, dated November 27, 1900, and in my-two contemporaneouslypendingapplications, respectively, for safe or vault doors, filed October31,1900, Serial No. 34,991, and safe or vault door mechanism, filedNovember 2, 1900, Serial No. 35,198.

In the drawings accompanying and forming a part of this specification,Figure l is a rear View of a safe or vault door with this improvedlocking mechanism applied thereto. Fig. 2 is a cross-sectional viewtaken in lines a a, Fig. .1. Fig. 3 is an interipr View of the backplate detached and reversed. Fig. 4c is a sectional view thereof, takenin line b b, Fig. 3. Fig. 5 is a view of the back plate detached andreversed, carrying a somewhatditferent form of locking mechanism. Fig. 6is a view illustrating the operation of this improved time andcombination locking mechanism, and Fig. 7 is a detail view of theclamping device for preventing too free movement of the worm-shaft.

Similar characters of reference indicate corresponding parts in thedifferent figures of the drawings.

The bolting mechanism shown herein is substantially similar to thatshown and described in my contemporaneously-pending application filedherewith and entitled Safe or vault door bolting mechanism, andtherefore only a general description thereof is deemed necessary herein.

The door in the present form shown comprises a body 2, having arearwardly-extending flange 3, usually provided with an offset 4. Tothis flange is secured a back plate 5, on which is preferably locatedvarious parts of the bolting mechanism, and which back plate alsocarries in the present instance the time and combination lockmechanism,(designated in a general way by A and hereinafter described.)i

The flange 3 is provided with a series of openings 6, located atintervals, each of which is shown of tapered or converging form,obtained by inclining one side wall of each opening. Working in each ofthese openings is a bolt 7, the shank of which is pivotally secured to arocking member 8, having wormteeth 9 located usually on a part of itsperiphery, but in the present instance shown entirely around suchperiphery. This rocking plate is mounted on a hub or projection rigidwith the back plate and is in mesh with a worm 10 of a worm-shaft 12,mounted in suitable bearings on the back plate. This worm is providedwith a bevel-gear 13, in mesh with asimilarly-formed gear 14, carried bya spindle 15, projecting at the front side of the door, and by means ofwhich spindle on the rotation thereof the worm-shaft will be actuated.To prevent the rotation of this worm-shaft except at the proper time,suitable controlling means is provided, shown herein in the form ofclutch mechanism, and in the present instance the gear 13 of theworm-shaft is carried by a loosely-mounted clutch member 16, rotatableon such shaft and effective to engage with a clutch member 17, splinedto such shaft, and which splined clutch member is controlled by the lockmechanism, hereinafterdescribed. For preventing too free action of theworm-shaft a friction device is provided, shown as-a bifurcated clamp18, secured to the back plate and encircling one end of said worm-shaft,whereby play thereof is prevented.

In the form herein shown and described, and which may be its preferredform, if desired, the lock mechanism in the present instance comprises atime-lock (designated in a general way by B) and a pair ofcombinageneral way It is, howtion-locks, (one designated in a as No. 1and the other as No. 2.)

ever, to be understood that this improved lock mechanism may in someinstances comprise a time-lock and one combination-lock. It is, however,preferable to provide a pair of combination-locks, since should one ofthem become inoperative for any reason the other can be utilized tooperate the bolt mech anism, thereby to unlock the door without thenecessity of forcing the same, usually requiring considerable time.Further, by providing a pair of combination-locks one may be permittedto respond to its combination and yet not be effective to unlock thesafe, thus showing that the proper combination had been divulged, butthat until the expiration. of the time set for the time-lock to operatethe safe or vault cannot be opened. In the form shown this improved timeand combination lock mechanism is connected with the splined clutchmember 17, whereby at the proper time such clutch member can be shiftedinto engagement with the loosely-mounted clutch member 16, thereby toform a positive connection between the bevel-gear of such loosely-mounted clutch member and the worm-shaft, so that on the operation ofthe spindle at the outer side of the door said worm-shaft can be rotatedto shift the bolts, which move in a lateral and radial or longitudinalpath and operate with a toggle action to draw the door to its seat withconsiderable force. Since in the present instance the combination-locksare the same, a description of one is deemed sufficient. Thiscombinationlock may be of any desired form and usually comprises aspur-gear20, mounted on the dialspindle, and which gear meshes with asimilar gear 21, the spindle or arbor of which carries a series ofbarrel-shaped tumblers 22, each having a notch. smaller gear 23, on thearbor 24 of which is mounted a fence 25, the hub thereof having teeth.This fence is so mounted that at cer-' tain periods the gear will turnindependently thereof, while at other periods friction Will cause suchfence to turn with the gear.

Mounted in the lock-case 26 is the usual bolt or actuator 27, providedwith teeth 28, meshing with the teeth of the fence. When thedial-spindle is operated, the tumblers will be rotated in the usualmanner until the notches of all the tumblers register with each other,

whereupon the fence will be shifted into po-I sition to have its endenter such notches, whereby it will be rotated with such tum-' blers toshift the bolt or actuator 27. Each of the bolts 27 in the presentinstance is connected with the splined clutch member 17 by' suitablemechanism, shown herein as a lever system, whereby the operation ofeither bolt 27 of either combination-lock will shift the splined clutchmember into position to engage the loosely-mounted clutch member in themanner hereinbefore set forth. The bolt or actuator of combination-lockNo. 1 is connected with the splined clutch member 17 by a lever 30,pivoted to such bolt and to a floating In mesh with this gear is adevice or bell-crank 31, which in turn is connected with aclutch-shifter 32, pivoted to the back plate,one end of suchclutch-shifter being in engagement with the splined clutch member. Thebolt or actuator of combination-lock No. 2 is likewise connected by alever 33, pivoted thereto and to such floating bell-crank. On the properoperation of combination-lock No. 1 it will be seen that the bolt oractuator 27 will be shifted into the position shown in dotted lines,Fig. 6, thereby moving the floating bell crank into the position shownin dotted lines, thereby to actuate the clutchshifter in the mannerindicated in dotted lines to shift the splined clutch member intoengagement with the loosely-mounted clutch member, the fulcrum for theproper operation of these levers being at the pivotal connection of thelever 33 with the bolt or actuator of combination lock No. 2. On theproper operation of combination-lock No. 2 the bolt-actuator will belikewise shifted into the position shown in dotted lines, thereby toshift the lever 33 into the position indicated in dotted lines,whereupon the floating bellcrank will be again moved into the positionindicated in dotted lines to actuate the cl ntchshifter in the mannerjust described.

From the foregoing it will be seen that on the operation of eithercombination-lock by one familiarwith the combination the splined clutchmember will be operated, thereby to permit the rotation of theworm-shaft by the spindle. Unless some means, however, is provided tonullify temporarily the control of the combination-locks over thedoor-bolting mechanism it would be possible to secure by duress thecombination from one familiar with it and utilize it to open the safe orvault. Therefore the combination-lock alone does not constitute absolutesecurity against the opening of the safe. By the provision of timelockmechanism, however, the operation of the combination-locks is notpossible until the time at which such time-lock mechanism is set to runhas expired. In the present instance the time-lock mechanism, which inone form comprises one time-lock, is connected with thecombination-locks in an improved manner.

For the present purpose it is deemed necessary only to show the actuatorof such timelock, which is designated herein as 50 and is usuallyprovided with a slot 51 for engagement with the device which is tobeactuated thereby, which in the presentinstance comprises alever 40,pivoted at one end to a stop member, such as alever 41,pivotailysecuredto the back plate and having a stop-face 42, adapted to engage acorresponding face 43 of the fence of combination-lock No. 1, wherebythe operation of this fence is prevented even though the combination beproperly set. The other end of this lever 40 is likewise connected witha stop member comprising a lever 44, pivoted to the back plate andhaving a stop-face 45, adapted to engage the bolt or actuator 27 ofcombination-lock No. 2, whereby the operation of this bolt is notpossible except as permitted by the time-lock. WVhen these stop membersare in the positions shown in full lines, Fig. 6, the operation of thefence of combination-lock No. 1 or the bolt of combination-lock No. 2 isprevented, so that even though the combinations were properly set theclutch-shifter would not be operated. When, however, the timelock hasrun the limit for which it was set, it will shift the lever 40 into thedotted-line position shown in said figure, thereby to actuate both thetwo stop members 41 and 44 into the dotted-line positions shown and freethe same from the fence of combination-lock No. 1 and the bolt ofcombination-lock No. 2, respectively, whereby on the proper operation ofeither combination-lock the clutch-shifter can be actuated in the mannerhereinbefore set forth.

To properlycounterbalance the mechanism of the time-lock, means isprovided for this purpose, which in the present instance comprises aspring 47, connected with the back plate and with one of the stopmembers, as 41.

In the form of time and combination lock mechanism shown in Fig. 5 thetime-lock mechanism comprises two time-locks B B one for controllingeach combination-lock. Each combination-lock is connected with theworm-shaft by separate means, and for this purpose the worm shaft isprovided with clutch mechanism comprising a pair of clutches, eachsimilar to that hereinbefore described, except that in place ofbevel-gears gears having spiral teeth are shown. The clutch -shiftingmeans comprises a pair of clutch-shifters, each of which is shown as aconnterweighted member 60, connected by a lever 61 with the bolt oractuator (not shown) of one combination-lock, it being pivoted thereto.The combination-lock No. l is connected with the time-lock B by asuitable lever 62, pivoted to the back plate and in engagement with theactuator 50 of said timelock, and which lever is shiftable to dog thefence (not shown) of said combination-lock No. 1, whereby on theexpiration of the time set for the time-lock to run this lever 62 willbe shifted to free the fence of said combination-lock N o. 1, andthereby permit the working of the clutch mechanism. The other time-lockB is provided with a stop member 65, which is in engagement with theclutchshifter of combination-lock No. 2,whereupon until the expirationof the time for which the time-lock is set to run the operation of thisclutch-shifter is not possible; but when the time-lock runs down thisstop member 65 will be carried into the position shown in dotted lines,whereby on the proper operation of combination-lock No. 2 theclutch-shifter will be operated to shift the splined clutch member intoengagement with the loosely-mounted clutch member on the Worm-shaft. Thetime-lock B in the form shown in said Fig. 5 directly dogs the fence ofcombination-lock N0. 1, while the time-lock B the bolt ofcombination-lock I claim as my invention- 1.
